Thank you all for the comments. I had a bit of a mishap and dropped the fuselage assembly, requiring a bit of keyhole surgery to re-attach some of the interior components. All sorted now and the repairs are only really noticable to me as I know where they are!
I also painted all the metalwork on the forward fuselage. This was a bit of a struggle as the circular hatches are too big for me to use my punch set to make masks, and too small for the circle cutter. I painted these by hand, and invariably there was some overspill. No matter how carefully I scraped off the excess (acrylic, over the Klear coated fuselage) there was some removal of the woodgrain. I touched this up with oil paint and a toothpick. Back in the cupboard for another 5 days to dry again! The metalwork will get a steel colour drybrush, then once sealed with more Klear, and generally weathered, the rough edges should be camoulflaged enough.
Meanwhile I have prepared the cabanes and wing struts, which have some stencil decals to apply, and I can work on the engine as well as fitting turnbuckles/eyelets to the wings prior to final assembly. The only parts left to make up are the guns and windscreen.
